Abstract
The invention provides a process for producing thin-layered adhesive non-porpous films of lacquer on metal surfaces. An aqueous suspension of a solid thermosetting synthetic resin which contains a special alkylphenyloxethylate and/or a special aminococonut fatty acid oxethylate as wetting agent and optionally extenders is used for the purpose. The synthetic resin is in the form of a fine powder with an average granular size from 0.1 to 10 .mu.m. The film is applied by immersion , spraying, coating, rolling or the like, and the curing is preferably effected at elevated temperatures. The use of mixtures of epoxide resins and phenol-formalehyde resins is preferred.
